Thread: iSCSI hook and IOMMU
Post: RE: iSCSI hook and IOMMU
| Well, the situation is that the kernel does not have a NIC driver, but configures the IOMMU. The INT13 hook is transparent and continues to function if the IOMMU is configured correctly. The way to re... |

Thread: iSCSI hook and IOMMU
Post: iSCSI hook and IOMMU
| I've observed issues when using iSCSI sanhook in conjunction with the IOMMU. When the loaded kernel enables the IOMMU, the traffic caused by the iSCSI hook eventually causes DMA faults, because the NI... |

Thread: UEFI boot and sanhook
Post: RE: UEFI boot and sanhook
| Oh yes, sorry. What I would like to do is use iPXE to hook an iSCSI disk, and then access it from within an EFI application. On legacy systems, this used to work. The kernel that was loaded by iPXE co... |

Thread: UEFI boot and sanhook
Post: UEFI boot and sanhook
| Hi,
I have a question about the hooking of iSCSI drives in iPXE when booting on UEFI machines.
On legacy systems, it was possible to transparently access the hooked drive using int13h. iPXE would ca... |
